Okay, a little real talk: Cavaliers are prone to a condition called mitral valve disease (MVD), a heart issue that eventually affects most of them. It’s the biggest reason their lifespan can be shorter than other small breeds. I know, it’s the part nobody likes to talk about, but knowledge is power!
The good news? Responsible breeders test for this, and early vet checkups can catch it. Think of it as giving your pup a regular “tune-up”. A healthy heart means more years of those goofy, head-tilting moments.
Other troublemakers include syringomyelia (SM), a spinal condition, and lots of ear infections (those floppy ears are cute, but they’re basically little moisture-trapping caves). But don’t panic—many Cavaliers live long, happy lives without major issues.
What Can You Do to Help Them Live Longer?
First off, find a brilliant breeder. A good one will show you health clearances for the parents, including heart and spine checks. It’s like checking a car’s service history before you buy it—except this car has fur and gives kisses.

Second, keep them lean. A chubby Cavalier is a cutie, sure, but extra weight is a huge strain on their heart and joints. Think of it this way: every extra pound is like them carrying a tiny, adorable backpack full of rocks. Not fun.
Third, exercise smart. They love walks, chasing squirrels (for about twelve seconds), and snuggling. They’re not marathon runners, so stick to moderate, fun activities. A tired Cavalier is a happy, healthy Cavalier.
And don’t forget regular vet visits. Your vet is the unsung hero of your dog’s life. They’ll catch heart murmurs early, clean those cave-ears, and tell you if your dog’s breath smells like a crime scene (spoiler: it usually does).
